SN65DSI86: question about SN65DSI86ZXHR

Part Number: SN65DSI86

Tool/software:

Hello：

May I ask a question? Currently, the registers of Ti chip SN65DSI86ZXHR have been captured. There is a difference between the normal and abnormal registers, and the 0x12 register. Could you please clarify the function of this register and what impact this difference may have? thank you!
The customer is currently experiencing a 30% sleep wake-up white screen issue in their project and needs to clarify and confirm the motherboard issue as soon as possible. Thank you！！！

    Hi Jimmy,

    Could you please share the I2C register writes of the initialization sequence. And what DSI clock rate is used in your application?

    Please check the 0xF1 - 0xF8 registers for reported errors in working and issue cases.

    What is the wake-up white screen related to? Is the input not sent DSI during that period or are they using Suspend mode?  Have the customer tested with internal test pattern and verified it works consistently?

    Best regards,
    Ikram
